HOISTING DEVICE.

Specification of Letters Patent.

Patented Nov. 18, 1913.

. Application filed February 13, 1913. Serial No. 748,210.

To all whom it may concern:

Be it known that I, JERRY A. VAUGHN, a citizen of the United States,residing at Montello, in the county of Marquette and State of Wisconsin,have invented certain new and useful Improvements in Hoisting Devices,of which the following is a specification.

My invention relates to the class of hoisting devices and moreparticularly to such a device adapted for use in connection with wagonsor other vehicles.

The primary object of the invention contemplates the provision of aspecially devised hoisting device wherein loading and unloading of heavyarticles upon vehicles is greatly facilitated, such device being soarranged upon the vehicle as to evenly distribute the weight of thearticle acted upon, regardless of its position. I

A further object of the invention resides in the provision of suitablemechanism carried solely by the vehicle at all times and whereby, duringone operation of the hoisting element, the article operated upon may besuccessfully hoisted to a desired elevation, and then conveyed to aposition above the floor of the vehicle.

A still further object of the invention is to provide mechanism of thischaracter which can be quickly adjusted to the desired working position,and which can be used effectively for the purpose of placing the articlehoisted, upon the floor of the vehicle as desired.

The above and additional objects are accomplished by such means as areillustrated in their preferred embodiment in the accompanying drawings,described in the following specification, and then more particularlypointed out in the claims which are alppended hereto and form a part ofthis app cation.

In describing my invention in detail reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is a side elevation of a device constructed in accordance with myinvention. Fig. 2 is a section on line 2-2 of Fig.

1, and Fig. 3 is a section on line 33 of Fig. 1.

Proceeding now to the description of the drawing, wherein is illustratedthe preferred form of my invention the numeral 1 designates a wagon uponwhich the hoisting device is mounted, the said Wagon being provided withstandards 2 for supporting a seat 3. While the device herein shown ispreferably mounted upon the wagon as illustrated in Fig. 1 of thedrawings, the same may be mounted upon anytype of vehicle whatsoever, asthe particular structure of the vehicle has nothing whatsoever to dowith the invention.

Upon the under side of the wagon floor and secured thereto through themedium of a plurality of bolts 4, I provide a pair of rack bars 5arranged in parallel spaced rela' tion upon the under side of thevehicle, the said bars being disposed in the same plane and to extendlongitudinally of the vehicle, and if desired formed either in one pieceor connected through the medium of a plate through which the bolts 4extend, thereby supporting the bars 5 in proper place, one near eachside of the vehicle. Adjustably mounted upon the said rack bars by meansof a transversely extending bar 7, area pair of upwardly extendingparallel beams 8, the said bar connecting the lower extremities of thesaid beams and normally fitting within the notches of the said bars 5.The said beams 8 may be of any desired length, and terminate at theirupper extremity in a cross beam 9 from which depends a double pulleyblock 10, the purpose of which will hereinafter fully appear.

Between the standards 2 and beneath the drivers seat a pair of drums 11and 12 are mounted, the upper drum 11 having a gear wheel 13 upon oneend thereof and a ratchet wheel 14 upon the opposite end thereof, whilethe lower drum 12 is likewise provided with a similar gear wheel 15 anda duplicate ratchet wheel 16, motion being imparted from the gear 13 tothe gear 15 or vice versa by means of a pinion 17 interposedtherebetween. Pawls 18 are pivoted as at 19 to one of the standards 2and normally engage the ratchet wheels 14 and 16 to prevent unwinding ofthe drums during the hoisting operation. In the preferred form but onecrank handle 20 is necessary in the operation of the drums, as the gearsand pinion are adapted to impart motion from one to the other of thedrums simultaneously.

A rope 21 is secured to the lower drum 12 and extends over one of thepulleys in the block 10 from which point, it depends to a second pulleyblock 22 where it pages over one of the pulleys provided therein. Therope 21 after passing over the pulley of the block 22 extends to theother pulley of the block 10 from which point it a ain depends to apoint 23 where it is secure in any suitable manner to the block 22. Anyform of grapple or hook 24 may be employed in connection with the block22 for the purpose of afiixing or attaching the article to be actedupon. The ropes 24 are secured to the drum 11, one near each end thereofand extend substantially parallel to a point 25 where they are securedin any suitable manner to the upper extremities of the beams 8 so as toswing the latter according to the rotation of the drum.

In operation, the article to be acted upon is first secured to the hook24, the beams 8 having been previously adjusted upon the rack bar 5 asdesired, whereupon the crank 20 is turned for imparting motion to thedrums 11 and 12. By such turning of the crank the ropes 21 and 24 aredrawn taut, the rope 21 lifting the weight from the ground or itssupport to the desired height, while the rope 24 swings the beams 8 uponthe bar 7, which acts as a fulcrum, until the said beams support theweight above the vehicle floor in the desired position. The paw'ls 18are then disengaged from the ratchet wheels 14 and 16 and the weightisdeposited upon the floor of the vehicle in the manner and place desired.

In practical application the pinion 17 may be eliminated and thespindles upon which the drums are mounted, provided with angularextensions upon which the crank 20 is adapted to fit. This operationwill necessitate a separate winding of each drum thereby causing theoperation of hoisting the weight to be entirely independent of theoperation for swinging the beams into proper position.

It will be seen from the above taken in connection with the accompanyingdrawings that by shifting the rod 7 upon the rack 5 as desired, properadjustment of the beams 8 is permitted; that the article acted upon maybe placed within the vehicle at any point desired; such action beingentirely controlled by the rotation of the upper drum 11; and that thelifting or hoisting of the article is controlled by the rotation of thelower drum 12.

While I have shown and described my invention as applied to a wagon, Idesire that the utilization of the device shall not be limited to such,as the mechanism comprising my invention may be readily applied to anysupporting structure whatsoever.

It will be understood that the above description and the accompanyingdrawings comprehend only the general and preferred embodiment of myinvention and that various minor changes in the details of construction,proportion and arrangement of parts may be made within the scope of theappended claims and without sacrificing any of the advantages of minvention.

Having thus fully escribed my invention, what I claim as new and desireto secure by Letters Patent, is

1. In a hoisting device, the combination of a supporting structure,parallel rack bars mounted in the same plane upon the said structure,upwardly extending beams longitudinally adjustable and pivoted to swingvertically upon said bars, and means including a pair of drums carriedby the said structure and connected to the said beams for swinging thelatter into adjusted position, as and for the purpose set forth.
